Hi all, Currently building a pc which is specific to a software that unfortunately requires either XP or Win 7 32bit to work correctly. Purchased new parts including an ASROCK A320M-HDV AM4 board. I downloaded and burned an official ISO from Microsoft for WIn 7 32bit and when it first enters the boot and is loading the OS install I get the error in the title. I've read it's something to do with these new BIOS not supporting correctly but the strange thing is that Win 7 64bit installs fine (have an official install disk here for that as well). I tried installing the 32bit from a USB stick with the USB install fix including within but same error. I also tried a different Win 7 32bit ISO to check it wasn't a bad file and that again had the same issue. So I'm a little perplexed as to why the 64bit version installs fine but the 32 is not. Can't find any settings in this bios for Win 7 compatability either which others with this issue have found to be a solution. Any ideas?
